SPECIFICATION forming part of Letters Patent No. 526,764, dated October2, 1894.

Application tiled March 7 1894:.

To a/ZZ whom t may concern:

Be it known that I, Josine WELDON, a citizen of the United States,residing at Elmore, in the county of Ottawa and State of Ohio, haveinvented a new and useful Sash-Holder, of which the followingis aspecification.

The invention relates to improvements in sash holders. i

The obj ect of the present invention is to improve the construction ofsash-holders, and to i provide a simple and inexpensive one, which willbe adapted to be readily applied toa window, and which will be positiveand reliable in operation, and capable of securely holding a sash at anydesired adjustment.

The invention consists in the construction andnovel combination andarrangementpf parts hereinafter fully described, illustrated in theaccompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure lis avertical sectional view of a sash holder,constructed in accordance with this invention, and shown applied to awindow. Fig. 2 is a transverse sectional view. Fig. 3 is a verticalsectional view on line m-- of Fig. 2. Fig. 4 is a detail perspectiveView of the bolt. Fig. 5 is a similar view of the mutilated gear wheel.Fig. 6 is a detail view of the spindle. Fig. 7 is a plan view of thesegmental plate. Fig. S is a detail View. of the pawl.

Like numerals of reference indicate corresponding parts in all thefigures of the drawings.

designates acasing,inserted in a mortise of a window frame and havingits outer end open to permit a sliding bolt 2, which is housed withinthe casing to engage a sash 3, whereby the latter is securely held atany desired adjustment. The sliding bolt is provided with a curved arm 4having an `outwardly extending portion arranged parallel with the bodyof the bolt, and having pivotally attached to it a cam head 5. The camhead 5 is provided on its inner face with perforated ears, between whichis secured a reduced p0rtion of the arm 4. The outer engaging convexface of the cam head 5 is provided with integral oppositely disposedteeth 6 having their outer ends shouldered. The upper teeth are adaptedto prevent the sash from accidentally falling, and the lower teeth areca- Serial No. 502,746. (No model.)

pable of preventing the sash from being raised.

The body of the bolt is provided at one side with a iiange 7, and at itsopposite side with a groove 8; and the casing is provided with a pair ofiianges 9, which fit in the groove of the bolt and against the flange 7,and serve as guides for the bolt. The bolt is provided at the inner sideof its bodywith a series of teeth 10, forming a rack,-7 and meshing witha mutilated gear wheel 11, which actuates the bolt. The gear wheel 11 ismounted on a spindle l2, and is provided with an integral toothedsegment 13, adapted to engage a toothed pawl14 to prevent accidentalrotation of the gear wheel, and consequent inward movement of the bolt,which would result in releasing the sash. The pawl is pivoted at itsinner or rear end, and has its main portion slightly curved to conformto the periphery of the segment, andits engaging face is provided withteeth corresponding with those of the segment, and shouldered to engagethe same. Aspring 15 engages the back of the pawl and holds it againstthe segment.

The spindle is provided with oppositelugs 16 and the gear wheel isprovided with an opening corresponding with the spindle, whereby whenthe spindle is turned the gearwheel is carried with the same. Theopening of the gear wheel is slightly larger at the extensions whichreceive the lugs 16 than the latter, to permit a slight movement of thegear wheel independent of the movement of the spindle; and a segmentalplate 17, provided with an opening 1S is pivoted to the gear wheeladjacent to the toothed segment thereof. The opening of the segmentalplate corresponds with that of the gear wheel, but is slightly largerthan the same, and when the segmental plate, which has a limitedmovement independent of the gear wheel, is moved outward to the end ofits movement the teeth of the segment 13 are exposed beyond theperiphery of the segmental plate, and can then engage the teeth of thepawl to lock the bolt against inward movement; but when the spindle isturned to carry the bolt inward the segmental plate projects beyond theteeth of the segment 13 sufficiently to ICO ment with the segment, inorder that the gear Wheel may turn freely. When the gear Wheel movesou-tward the beveled portions of the opposed teeth engage and readilypass on another.

The outer end of the spindle issquared in order that the holder may bereadily operated operation, and that it is capable of securely holding asash at any desired adjustment.`

What I claim is- 1. In a sash holder, 'the combination of a casingprovided with flanges forming guides, a sliding bolt mounted inthecasin'rg and havj ing a ange and a :groove to t said .anges, l andprovided with an outward extending arm odset from the body of the bolt,said bolt being provided with a rack, a cam pivoted to the youter end ofsaid arm and adapted to engage a sash, and a gear Wheel meshing with therack of the bolt for actuating the latter, substantially as described.

2. In a sash holder, the combination of a casing, a sliding bolt mountedtherein and provided with a rack, a gear wheel meshing With the rack andprovided with a toothed segment, a pavvl arranged to engage the teeth ofthe segment, and a plate carried by the ,l gear wheel, but having alimited movement Changes in the form, proportion and the minor detailsof construction may be resorted to without departing from the principleorsacrificing any of theadvantages `of this inindependent thereof, andbeing of such a size and shape as to project beyond the teeth of thesegment and engage the pawl, substantially as and for the purposedescribed.

In testimony that I claim the foregoing as i my own Lhave hereto afiixed.my signature in the presence 4'ot' 'two witnesses.
